COMBINED STOVE-PIPE THIMBLE AND FASTENER.

SPECIFICATION forming part of Letters Patent No. 417,531, dated December17, 1889.

' Application filed April 11, 1889. Serial No. 306,809. (No model.)

.Z 0 all whom it mayconocrn:

Be it known that I, JOHN BAER, of Buffalo, in the county of Erie andState of New York, have invented certain new and useful Improvements ina Combined Stove-Pipe Thimble and Fastener; and I do hereby declare thatthe following description of my said invention, taken in connection withthe accompanying sheet of drawings, forms a full, clear, and exactspecification, which will en able others skilled in the art to which itappertains to make and use the same.

This invention has general reference to improvements in combinedstove-pipe thimbles and fasteners; and it consists, essentially, in thenovel and peculiar combination of parts and details of construction, ashereinafter first fully set forth and described, and then pointed out inthe claims.

In the drawings already mentioned, which serve to illustrate my saidinvention more fully, Figure 1 is an elevation of my improved combinedthimble and fastener for stovepipes. Fig. 2 is a transverse sectionalelevation in line at at of Fig. 1. 7

Like parts are designated by corresponding letters of reference in boththe figures.

The object of this invention is the production of a cheap, simple, andconvenient thimble and fastener for stove-pipes. To accomplish thisobject, I construct my combined stove-pipe thimble and fastener,essentially, of a cylindrical shell A of a diameter a trifle larger thanthe largest size of pipe that it is to accommodate, and fasten to eachend of this cylinder a flange B B, respectively, said flanges havingperforations O, to receive the plaster H, and thereby to enable thelatter to obtain a good hold on the (preferably metallic) surface ofwhich said flange is composed.

In the face of the collar or flange B, I provide for a rise orprojection D of a height corresponding to the thickness of the saidplastering and the hard finish I usually give to the same, the object ofsaid rise being to provide for the marking of the date of patent thatmay begranted on the device and for other advertising matter that Idesire to appear on the flange, and which could not be seen unlessraised high enough to be level with said plaster and finish. In the rearflange B there is an inwardly-projecting lug E, to which are securedthree bars F F F", respectively, the bar F being placed midway betweenthe bars F F in such a manner that a stove-pipe G, if pushed with itsend between said bars, will be slightly deflected or notched or crimped,as shown at J in Fig. 2, and held by frictional contact between saidbars as tightly as is necessary to retain its position under allordinary circumstances. It will now be observed that, owing to the factthat the three bars F F F are located close to the shell A, it ispossible to place between the same stove-pipes of all sizes smaller thanthe largest size to which the thimble is adapted, a smaller size beingshown in dotted lines in Fig. 1, and that when said pipe or pipes arepushed back as far as the lug E on the end of said shell itwill form astop for the stove pipe and prevent it from being pushed into the flueK. To facilitate the entering of the pipe G between the forks of thebars F F F, the bar F is slightly curved, as shown at f in Fig. 2. Itwill now be further observed that, owing to the bars F, F, and F" beingfastened at but one end and the bars being of but small diametercomparatively, their unsecured end is adapted to spring and thereby toact as spring-jaws to hold the stove-pipe between the adjacent sides ofsaid bars in a manner readily comprehended.

The combined stove-pipe thimble and fastener, as heretofore described,may be readily manufactured in cast-iron and sheet metal, and it may besold at a cost but a trifle above that of an ordinary thimble.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent of the United States- 1. As an improved articleof manufacture, a combined stove-pipe thimble and fastener consisting ofthe shell A, having the flange B, and a clamp for the stove-pipe,consisting of the rods F F F, fastened with one end to the said thimble,as and for the purpose set forth.

2. In stove-pipe thimbles and fasteners, the clamp for holding saidpipe, consisting of the rods F F F, the shell A, and the lug E, saidrods secured within said shell with one end to the said lug E, andadapted to receive the stove-pipe between the adjacent sides of saidbars, as and for the purpose stated.

3. In stove-pipe thimbles, the combination, with the shell A, having theflanges B B, of the clamp and stop combined, consisting of the threebars F F F, secured to the lug E with one end and adapted to receive thepipe G between their ad jaeent sides, as and for the purpose set forth.
